CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

The present application is related to and claims priority under 35U.S.C. §119(a) to Korean Application Serial Nos. 10-2014-0072089 and10-2014-0128539, which were filed in the Korean Intellectual PropertyOffice on Jun. 13 2014 and Sep. 25, 2014, respectively, the entirecontent of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method and device for selecting acommunication service to connect communication by user equipment in acommunication system.

BACKGROUND

The Internet, which is a human centered connectivity network wherehumans generate and consume information, is now evolving to the Internetof Things (IoT) where distributed entities, such as things, exchange andprocess information without human intervention. The Internet ofEverything (IoE), which is a combination of the IoT technology and theBig Data processing technology through connection with a cloud server,has emerged. As technology elements, such as “sensing technology”,“wired/wireless communication and network infrastructure”, “serviceinterface technology”, and “Security technology” have been demanded forIoT implementation, a sensor network, a Machine-to-Machine (M2M)communication, Machine Type Communication (MTC), and so forth have beenrecently researched.

Such an IoT environment may provide intelligent Internet technologyservices that create a new value to human life by collecting andanalyzing data generated among connected things. IoT may be applied to avariety of fields including smart home, smart building, smart city,smart car or connected cars, smart grid, health care, smart appliancesand advanced medical services through convergence and combinationbetween existing Information Technology (IT) and various industrialapplications.

User equipment widely used in mobile communication markets generally hasa flight mode implemented therein in order to readily interrupt allcommunication functions in a space where communication is not allowed,for example, in a space of an airplane while taking off or landing. Theflight mode can be set by a user on the screen of a smart phone orthrough a specific physical button, etc. In the flight mode, the userequipment disables transmission and reception functions of all remoteand short-range communication. Examples of the remote communicationinclude commercial mobile communication systems, such as Global Systemfor Mobile communication (GSM), Wideband Code Division Multiple Access(WCDMA), Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A),and the like, and examples of the short-range communication includecommercial mobile communication systems, such as Wireless Fidelity(WiFi), BLUETOOTH, and the like. FIG. 1 illustrates an example of amethod for setting a flight mode of a smart phone. User equipment 100has a touch screen 105 on the front surface thereof, and a user inputsdesired information by touching the touch screen. The touch screendisplays a control screen for starting or stopping several functions,and the control screen includes a flight mode icon 110. The user sets ordisables a flight mode by touching the flight mode icon. In addition,the user also displays a screen for setting or disabling the flight modeby clicking a specific physical button implemented in the userequipment. Through various methods in addition to the above-describedmethods, the existing user equipment interrupts all communication.

In the existing flight mode, the user equipment interrupts all thecommunication. However, the user may also want to interrupt only somecommunication rather than all the communication according to situations.For example, there is a case where an incoming call is unacceptable ineveryday life. The user is not willing to receive an incoming call in aplace that requires silence or when an undesired person makes a call tohim or her. In the situation where the user cannot receive the incomingcall, a ring tone or vibration for the incoming call is unnecessary.Accordingly, in the situation described above, a communication modeappropriate for the user's situation is required.

A Universal Integrated Circuit Card (UICC) is a smart card inserted intoa mobile communication terminal. The UICC stores private information ofa mobile communication subscriber, authenticates the subscriber, andcreates a traffic security key when the subscriber accesses a mobilecommunication network, thereby making it possible to stably use themobile communication.

The UICC is manufactured as a dedicated card for a specific mobilecommunication service provider according to the corresponding serviceprovider's request and released with previously loaded authenticationinformation, for example a Universal Subscriber Identity module (USIM)application, International Mobile Subscriber Identity (IMSI), a K value,and the like, for the network access of the corresponding serviceprovider. Accordingly, the corresponding mobile communication serviceprovider receives delivery of the manufactured UICC to provide it to thesubscriber, and thereafter performs the management, such asinstallation, modification, deletion, and the like, of an application inthe UICC using technologies such as Over The Air (OTA), etc. whennecessary. The subscriber inserts the UICC into the mobile communicationterminal of his or her own to use the network and application servicesof the corresponding mobile communication service provider, and whenreplacing the terminal, the subscriber moves the UICC from the existingterminal to a new terminal to use the authentication information, themobile communication phone numbers, the personal telephone number list,and the like, which are stored in the UICC, in the new terminal as theyare.

The standardization group, called European Telecommunications StandardsInstitute (ETSI), defines the physical shape and the logical function ofthe UICC to maintain the international compatibility thereof. In termsof a form factor that defines a physical phenomenon, from the mostwidely used mini-SIM to a micro-SIM and a recently used nano-SIM, thesize thereof becomes smaller. Although it contributes much to thecompactness of a mobile communication terminal, it is expected that aUICC smaller in size than a recently established nano-SIM is difficultto standardize because a user is likely to lose it. Since the terminalrequires a space for mounting a detachable slot due to a characteristicof the detachable UICC, further compactness is expected to be difficult.

In order to solve such a problem, a demand for replacing the UICC byembedding a security module performing a similar function to the UICC ina mobile communication terminal when manufacturing the terminal isemerging. Accordingly, an embedded Universal Integrated Circuit Card(eUICC) structure, which is a UICC that cannot be detached, is proposed.

DETAILED DESCRIPTION

FIGS. 1 through 40, discussed below, and the various embodiments used todescribe the principles of the present disclosure in this patentdocument are by way of illustration only and should not be construed inany way to limit the scope of the disclosure. Those skilled in the artwill understand that the principles of the present disclosure may beimplemented in any suitably arranged wireless communication device.Hereinafter, exemplary embodiments of the present disclosure will bedescribed in detail with reference to the accompanying drawings.Further, in the following description of the present disclosure, adetailed description of known functions and configurations incorporatedherein will be omitted when it makes the subject matter of the presentdisclosure rather unclear.

The present disclosure gives a description of technology for telephonecall and message control. User Equipment (UE) includes a mobilecommunication terminal such as a cellular phone, a smart phone, and thelike.

Hereinafter, the present disclosure relates to a device and method forsubscribing to a network in a wireless communication system.

A messenger mode in the present disclosure is a mode for permitting onlycommunication relating to a specific communication service. For variousreasons, a user wants to interrupt only some communication. One of themis an incoming call. In an environment requiring silence, the user wantsto interrupt only the incoming call causing noise and vibration. Or whenthe user does not want a spam call, the sender of which cannot beidentified, noise or vibration is unnecessary for the user. In caseswhere the battery residual quantity of user equipment is small, a voicecall communication service causes the battery to be rapidly discharged.Accordingly, it is necessary to permit only a text message or anapplication messenger communication service that restrictively uses thebattery. Lastly, for a user's special purpose, for example, forcommunication between doctors in a hospital, a pager is still used, anduser equipment also needs to provide a similar function. Accordingly, inconsideration of the aforementioned user requirements, variousembodiments of the present disclosure propose a technology forselectively interrupting only some functions. For example, userequipment, according to various embodiments of the present disclosure,interrupts a general incoming call communication service and permitsonly a text communication service, such as an SMS or MMS, and amessenger application messenger communication in a messenger mode.

An existing text message like an SMS or MMS is permitted in a messengermode. Although an incoming voice call is interrupted according tovarious embodiments of the present disclosure, an incoming voice callfor a telephone number designated by a user is discriminatorilypermitted. When the user designates a telephone number in advance, acall for the designated telephone number is permitted rather than beinginterrupted. Currently used user equipment utilizes a messengercommunication service provided in an application form, in addition to anexisting SMS or MMS text message. Many messenger communication servicesare introduced to markets, and a subscriber exchanges text messages withdesired counterparts using an IP Internet network. CHATON SQUARE, SKYPE,KAKAOTALK, GTALK, and the like are examples of such messengercommunication services. Communication is also permitted for allmessenger applications or only for limited applications designated inadvance by a user. The reason for permitting the communication only forthe limited applications is to prevent a smart phone from consistentlyperforming communication due to an unintended application.

Since an incoming voice call is usually interrupted in a messenger mode,according to various embodiments of the present disclosure, it ispossible to more flexibly set a communication system for supporting themessenger mode. For example, an LTE system identifies whether paging isreceived, at every Discontinuous Reception (DRX) period. As the DRXperiod is set to be longer, it is advantageous for saving the powerconsumption of user equipment. However, a voice call connection isdelayed due to the DRX period set to be longer. When an incoming voicecall is excluded, the power consumption of the user equipment can besignificantly saved by setting the DRX period to be very long. In thecase of a text message or a messenger communication service, a degree ofdelay is less sensitive, compared to in the case of a voice call. When auser sets a messenger mode, user equipment reports the messenger mode toa network and receives setting information according to that themessenger mode.

FIG. 2 illustrates an example of displaying a messenger mode in a UEaccording to various embodiments of the present disclosure.

A user sets or disables a messenger mode by simply clicking a controlicon of the messenger mode in a UE. The user also displays the controlicon 205 using a physical button. A UE manufacturer or the user displaysthe control icon 205 on a screen 200 by performing a series of touchscreen or motion operations in advance. The control icon of themessenger mode is also displayed on the screen by pressing the physicalbutton 230 of the UE for a predetermined period of time. The physicalbutton is a multi-purpose button, such as the power button of the UE ora separate physical button. A control icon 225 of the messenger mode isdisplayed by pressing the physical button and control icons for otherpurposes, namely, an end icon (210), a restart icon (215), and a flightmode icon (220) are displayed at the same time. The end icon (210) isused to shut off the power of the UE, the restart icon (215) is used torestart the UE, and the flight mode icon (220) is used to interrupt thecommunication of the UE. In addition, through a separate physicalbutton, the UE is switched to the messenger mode with one-click.

FIG. 3 illustrates an example of a display method in the setting of amessenger mode for a UE according to various embodiments of the presentdisclosure.

When a user switches the UE from a general communication mode to themessenger mode, it is displayed on the screen of the UE. This is to helpthe user consistently recognize the mode of the UE, thereby enabling theuser to switch the messenger mode to the general communication modeagain when it is necessary to receive an incoming voice call. The UEdisplays the status and a notification bar on the screen thereof. Invarious embodiments, the notification bar is located on the upper sideof the screen 300, and an indication (305) for notifying of theactivation of the messenger mode is displayed on the notification bar.The indication is applied to both a general screen and a locked screenof the UE. At a predetermined location on the locked screen 310 of theUE, the activation of the messenger mode is also displayed to be large.When the user does not touch the screen of the UE for a predeterminedperiod of time, the UE switches to the locked screen. The locked screenis for preventing the UE from performing an unintended operation throughthe user's unnecessary screen touch, and is displayed as a lock icon315. The UE switches the locked screen to a general screen through aclick or motion on the icon. The user identifies a messenger modeindication 320 on the locked screen without having to switch to thegeneral screen to recognize that an incoming voice call is beinginterrupted. Furthermore, when the user touches the messenger modeindication, a control icon for switching to the messenger mode isimmediately displayed, thereby simplifying a mode switching procedure.In addition, a messenger-mode dedicated screen is also introduced. Onthe messenger mode screen, permitted messenger applications are alsohighlighted as indicated by reference numeral 330, in addition to thedisplay of the messenger mode activation state 325.

Embodiments of the present disclosure propose network control signalingfor supporting the above-described messenger mode. When an incomingvoice call, an SMS/MMS text message, and an application messenger areprovided to a specific user in the messenger mode, signaling andoperations performed by related network entities are different from eachother. The present disclosure employs a new signaling message forsupporting the messenger mode and a new network server for supportingthe messenger mode. In the present disclosure, the new network server isreferred to as a ‘messenger mode server.’ In addition, the messengermode server decodes collected data and distinguishes between data of amessenger application to transfer only message data of a permittedapplication messenger to a specific UE.

FIG. 4 illustrates an example of a control procedure for an incomingcall according to various embodiments of the present disclosure. In FIG.4, it is exemplified that a user of UE 2 415 attempts to make a voicecall to a user of UE 1 400 according to various embodiments of thepresent disclosure.

Referring to FIG. 4, in operation 420, UE 1 400 switches to a messengermode according to the user's specific intention or setting. The settingincludes at least one of a setting for receiving Access Class Barring(ACB) information from a base station and automatically switching to amessenger mode when an access priority is low to reduce the consumptionof a battery, and a setting for automatically switching to a messengermode in the case of a specific place and time.

In operation 425, UE 1 400 transmits a messenger mode activation requestmessage to a call session control server. The call session controlserver includes a Call Session Control Function (CSCF) 405 or a MobilityManagement Entity (MME). The call session control server functions tohandle a part relating to call and session processing and serves as agateway for an incoming call. The request message is for informing thecall session control server 405 that the UE switches to the messengermode. In addition, the message includes a list of messenger applicationsthat the user is using, and a list of uninterrupted telephone numbers.The message includes a list of messenger applications that are not usedby the user, and a list of telephone numbers to interrupt. The requestmessage is used for selectively providing a communication service to theUE.

In operation 430, the call session control server 405 stores thetelephone number list included in the message. In operation 435, thecall session control server 405 transmits a messenger mode applicationmessage to a messenger mode server. The message includes the messengerapplication list. At the same time, in operation 440, the call sessioncontrol server 405 selectively provides new setting information to UE 1400. The new setting information includes setting information to which avery long DRX period is applied to maximize power consumption.

When UE 2 415 attempts to make a voice call to UE 1 400 in operation445, information on the voice call attempt is reported to the callsession control server 405, and in operation 450, the call sessioncontrol server 405 determines whether to transmit a paging message forestablishing the voice call to UE 1. To this end, the call sessioncontrol server compares a pre-stored telephone number list with theoriginating telephone number. If the originating telephone number existsin the list, the user of UE 1 400 has to be notified of the telephonenumber despite the messenger mode of UE 1. In operation 455, the callsession control server 405 transmits a paging message to UE 1 400. Ifnot, the voice call has to be interrupted.

In operation 460, the call session control server 405 requests themessenger mode server 410 to process the interrupted call. The messengermode server 410 functions to inform the user of UE 2 415 that the callhas been interrupted due to the activation of the messenger mode in UE1. The messenger mode server 410 additionally provides a method ofcommunicating with the user of UE 1 400. To this end, in operation 465,the messenger mode server 410 transmits, to UE 2 415, an acknowledgementmessage including the messenger mode activation information of thecounterpart and the messenger application list.

In operation 470, UE 2 415 automatically displays the activation ordeactivation of the messenger mode of the counterpart and the messengerapplication list to the user. The user of UE 2 (415) creates a messageusing an SMS/MMS text message or the messenger application.

In operation 475, UE 2 415 transmits the message to UE 1 400. If thecreated message is an SMS/MMS text message, the message is transmittedto the call session control server 405 and then provided to UE 1 400.

In cases where the user of UE 1 400 disables the messenger mode inoperation 480, UE 1 400 transmits a messenger mode deactivation messageto the call session control server 405 in operation 485.

In operation 490, the call session control server 405 deletes thetelephone number list. In operation 495, the call session control server405 transmits the messenger mode deactivation message to the messengermode server to inform that UE 1 400 has disabled the messenger mode.

FIG. 5 illustrates an example of a method of displaying a message or amessenger after the interruption of an incoming call according tovarious embodiments of the present disclosure. When UE 2 415 identifies,in operation 470 of FIG. 4, that UE 1 400 of the user who wants to makea voice call is in the messenger mode, UE 2 415 immediately displays, onthe screen thereof, a list of a text message application 500 andmessenger applications 505, 510, 515, and 520, through whichcommunication is possible, in order to reduce the operating procedure ofthe user of UE 2. When the user of UE 2 selects one of the text messageapplication and the messenger applications in the list, UE 2 415switches to a dialogue window of the selected application and sendmessages to the user of UE 1 400. In order to further reduce the user'soperating procedure, UE 2 415 identifies the messenger mode of UE 1 400and then immediately displays, on the screen thereof, a text messagewindow or a dialogue window of a messenger application that has beendesignated in advance by the user. The dialogue window of the messengerapplication basically includes dialogue boxes 525 for displayingdialogue contents sent by the users of UE 1 400 and UE 2 415, an inputwindow 530 for receiving an input of a dialogue, and a send button 535for instructing an input dialogue to be sent.

FIG. 6 illustrates an example of a procedure of receiving an applicationmessage in a messenger mode according to various embodiments of thepresent disclosure.

In FIG. 6, a specific communication service provider, for example, amessenger provider or an e-mail provider 615 attempts to provideapplication data to a user of UE 1 600.

In operation 620, the user of UE 1 600 switches to a messenger modeaccording to his or her specific intention. In operation 625, UE 1 600transmits a messenger mode activation request message to a call sessioncontrol server 605. The call session control server 605 functions tohandle a part relating to call and session processing and serves as agateway for an incoming call. The message is for informing the callsession control server 605 that the UE switches to the messenger mode.The message includes a list of messenger applications that the user isusing, and a list of uninterrupted telephone numbers. The messageinformation is used for selectively providing a communication service tothe UE. In operation 630, the call session control server 605 stores thetelephone number list included in the message.

In operation 635, the call session control server 605 transmits amessenger mode application message to a messenger mode server. Themessage includes the messenger application list.

The controller restricts an incoming callaccording to incoming call interruption information, performs paging tothe UE for an incoming call included in the non-message mode appliedtelephone number list, and forwards a call processing message to amessenger mode server for an incoming call not included in thenon-messenger mode applied telephone number list.

The messenger mode is also used when the UE accesses a mobilecommunication network using an embedded Universal Integrated CircuitCard (eUICC).

FIG. 15 illustrates an example of a wireless communication methodbetween a UE and a communication service provider according to variousembodiments of the present disclosure.

Referring to FIG. 15, FIG. 15 (a) illustrates a case in which a userconnects to a wireless communication network through a UniversalIntegrated Circuit Card (UICC). In FIG. 15 (a), a UE 1510 communicateswith a mobile communication service provider 1530 using a UICC 1520. TheUICC 1520 provides a service only for a specific mobile communicationservice provider since only authentication information for the networkaccess of a one specific mobile communication service provider isincluded in each UICC. Therefore, the user accesses the network of thespecific mobile communication service provider 1530 according to theUICC 1520 by inserting the UICC 1520 into the UE 1510.

FIG. 15B illustrates a case in which a user connects to a wirelesscommunication network through an embedded Universal Integrated CircuitCard (eUICC). In FIG. 15 (b), a UE 1550 communicates with a mobilecommunication service provider 1570 using an eUICC 1560. Unlike the UICC1520 providing only a service for a predetermined specific mobilecommunication service provider, the eUICC 1560 allows the user todetermine a specific mobile communication service provider among aplurality of mobile communication service providers to use a servicethat the corresponding communication service provider provides. When theuser requests the specific mobile communication service provider 1570 toprovide a service, using the UE including the eUICC 1560 embeddedtherein, the specific mobile communication service provider 1570requests a profile providing server 1580 to download a profile, and theprofile providing server 1580 encrypts the profile of the specificmobile communication service provider 1570 and then transfers the sameto a profile managing server 1590. When the profile managing server 1590transfers the encrypted profile to the eUICC using the Over The Air(OTA) technology, the UE 1550 downloads and installs the receivedencrypted profile to access the network of the specific mobilecommunication service provider 1570.

The eUICC 1560 has an eUICC Identifier (eUICCID), a secret key, and anOTA key recorded therein and includes a plurality of storage spaces. TheeUICCID is unique identification information of the eUICC 1560 that istransferred to a network provider when the user subscribes to thenetwork provider. The secret key is an encryption key for the eUICC1560, which is used when a profile is encrypted and transferred to theeUICC 1560. The OTA key is a key for the management of the eUICC 1560,which is used for secondary encrypting of the eUICC profile.

Each of the storage spaces is used for storing a profile, and theprofile store information included in the UICC. For example, the profileincludes Universal Integrated Circuit Card Identifier (UICCID)information, Universal Subscriber Identity Module (USIM) information,banking information, and the like. A profile generated from a specificnetwork provider is stored and activated in any one of the storagespaces so that the eUICC functions as an eUICC of the network provider.

Through the wireless communication network access using the eUICC, theuser selects a specific mobile communication service provider among aplurality of mobile communication service providers to receive awireless communication network service. In order to select the specificmobile communication service provider, the user accesses an intermediaryserver that sells a mobile communication network service.
